I walk a lot; the best way to experience a city. So it's sometimes to do with the way places join up. This cast concrete letterform is a part of the Lycée's gateway. Each of the form's facets arrives at a different character, so six possible letters come from each cast object. I've never been inside the Lycée but always walked through this way up to the V&A, in order to examine again and again how each form works. The surfaces set the tone for the V&A and its incredible Ceramics floor, a perennial inspiration.

The power station is a ghost like ruin that stands on the banks of the Thames. Its right next to the train tracks rolling out of London to the rest of the south of England. I pass it every time I go back to where I grew up and every time I arrive back in London. It has become symbolic with arriving and departing, a constant in my life. I used to joke and refer to it as my lover - seeing me off and welcoming me home.

Designed by Wells Coates, the Isokon Building opened in 1934 and was the first apartment block to be built using reinforced concrete. The Isokon Gallery is open at weekends telling the story of the Isokon building, the pioneering modern apartment block as an experiment in new ways of urban living.

South London is largely underrated considering at times it's a treasure chest of gems; Battersea Park is one of those big sparkly ones. An interesting mix of faultlessly pruned gardens, displaced architecture, shape, form and colour generate a delightfully influential weekend stroll. With views of the almighty Battersea Power Station and the river dividing you from the Chelsea Embankment.

Just above the Dorfman Theatre lobby at the National Theatre, is the entrance to the high-level walkway, a public walkway that overlooks the National Theatre props and scenic workshop. It's free and is a unique chance to get a glimpse of what happens backstage. I love popping in when I'm on the south bank, as you get a completely different sight each time, depending on which production the workshops are working on at the time.
